Typical water visibility

Summer visibility around Big Sur is commonly reported in the 15–40 ft range, a community-guidance estimate, not a measurement. Rain, river discharge, swell mixing, and seasonality can shift real conditions dramatically day to day.

That's exactly why Submarius exists. The in-app clarity forecast blends satellite turbidity (NOAA CoastWatch Kd490), river-plume detection (USGS), wave-mixing physics, and community post-dive reports to estimate how far you'll actually see tomorrow, with explicit uncertainty bounds, not a seasonal average.
